Technical description

The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allows local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
